4 In the United States, traffic signal timing is traditionally developed to minimize motor vehicle delay at signalized intersections, with minimal attention paid to the needs of pedestrians and bicyclists. The unintended consequence is often diminished safety and mobility for pedestrians and bicyclists.

Understanding User Needs and Establishing Priorities 5 • Pedestrian calls/Traffic signal controller data: Pedestrian detections and/or calls at an intersection can provide insights on the demand profile across the day and by direction. Traffic signal controllers with data-logging capabilities can record the number of times a pedestrian call was placed for intersections using pedestrian pushbuttons.

6 Traffic Signal Control Strategies for Pedestrians and Bicyclists Pedestrian and cyclist needs that should be addressed in the design of traffic signal timing plans and traffic signal equipment can be grouped into the following four categories: • Safety and comfort • Minimizing delay • Ease of use and information • Accessibility 2.2.1 Safety and Comfort Pedestrians and cyclists should be able to cross intersections with little risk of crash or injury. With motor traffic, safety is often measured in terms of crashes because motor vehicle volumes are typically so great that any underlying safety risk will readily be manifested in crash statistics.

Understanding User Needs and Establishing Priorities 7 minimizing pedestrian delay. The current framework of traffic signal timing design needs to be changed to one that aims to minimize pedestrian and bicycle delays as well as motor vehicle delay.

8 Traffic Signal Control Strategies for Pedestrians and Bicyclists 2.2.4 Accessibility Intersection crossings should be accessible to all pedestrians, including those with disabilities. Persons with vision impairments especially rely on walking and transit for their mobility because they may have additional challenges operating motor vehicles or riding a bicycle.
